WVILLIAM F. KIESEL, JR, OF ALTOONA, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 789,155, dated May 9, 1905.

Application filed November 17,1904. Serial No. 233,117.

To (1U whom it may concern:

Be it known that I,WILLIAM F. KIEsEL, J r., a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Door-Operating Gear for Side-Dump Cars, of which the following is a specification.

This invention relates to improvements in the mechanism by which the doors which close the openings from the chutes in side-dump cars are opened and closed; and it is applicable more particularly to cars used for transporting coal, coke, and ores, and having side delivery-chutes constructed in the manner described in my United States Letters Patent No.726,169, dated April 21, 1903, for improvements in steel-car construction.

The object of my present invention is to provide new and improved mechanism whereby the doors on the two sides of the car will be simultaneously opened or closed by means of a single operating-shaft manipulated from one end of the car and whereby the doors will be securely locked in both their opened and closed positions.

I attain my object by means of the construction and arrangement of the several parts of the operating-gear, as illustrated in the accompanying drawings, in which Figure 1 represents a side elevation of a portion of the doors and operating-gear, the body of the car being represented by broken lines; Fig. 2. a plan view of the operatinggear, the delivery doors and chutes being shown sectioned on a line just below the center sills of the car; Fig. 3, a vertical transverse section taken between the deliverychutes; Fig. 4, a similar view taken at the end' of the chutes nearest the operating-shaft connection; and Figs. 5 to 10, inclusive, details showing on an enlarged scale the relative arrangement and construction of the operating sheaves, links, and guides. 4

Like letters of reference designate like parts in the several views.

In Fig. 1 is shown a portion of a car such as described in my said Letters Patent, the openings from the side delivery-chutes being closed by substantially vertically-h ung doors A, supported by hinges at B.

The inclined chutes are indicated at O in Figs. 2, 3, and 4. In order to hold the doors closed against the weight of the contents of the car, a strong and efficient closing mechanism must be employed both to operate the doors and to hold them locked when in closed position. It is also desirable to lock them in full open position. To accomplish this, I provide at each side of the doors operating-links E, which are coupled to pins or trunnions D, which project beyond the sides of the doors. The inner ends of the links E are coupled to cross-heads F, adapted to slide between the guides H, formed by anglebars riveted to the sides of the chutes. The guides at the outer sides of the end chutes are formed of double angle-bars I, and the crosshead G is provided with vertical guideways to engage this form of guide. The construction of these cross-heads and guides is shown more clearly in Figs. 8 and 9. The crossheads F and G are coupled to crank-arms on operating-sheaves K and L by means of the slightly-bent links J. The sheaves are supported by hangers M, which are fastened to plates N, secured to the under side of the center sills O, the manner of mounting the sheaves in the hangers being shown in Fig. 6. At the under side of the sheaves and at one side of the center is a depending web P, strengthened by cross-ribs. Arms Q project out from the lower flange of the sheave and from a horizontal shelf supported by the web P and form a crank, to which one of the arms J is coupled. From the shelf under the sheave at the opposite side of the crank-arms Q a vertical supportingweb R projects downward, and the arms S are carried out from the shelf and from this depending web R form the crank for the second link J, the crankarms S and Q being so positioned that their centers will lie diametrically opposite one another. The sheaves are operated by means of chains or cables which are coupled to reciproeating bars U U, supported on guide-brackets V at opposite sides of the sheaves K. These reciprocating bars run longitudinally from end to end of the chutes and are supported on the guideways W, formed on the brackets V, the chains from the sheaves running through grooved channels X, formed at the side of each of the guideways. The ends of the chains are attached to adjustable bolts secured in eyeblocks Z, attached to the reciprocating bars U. The chains are also fastened to the sheaves by bolts passing through holes provided therefor in the groove of the sheave at the point Y, as shown in Fig. 5. By this arrangement a half-revolution of the sheaves is provided for and the chains as they run on and off from the sheaves are ljiept in line with the grooves thereon by means of the guideways X on the brackets V. Any slack in the chain is taken up by means of the adjustingbolts in the eye-blocks. One of the end sheaves is made double, as indicated at L in Figs. 1, 2, and 4E, and from the upper half of this double sheave a chain or cable runs over guidepulleys ft to a chain-worm 5, carried by the operating-shaft c, which runs in at an angle from the end of the car and is supported upon suitable brackets attached to the upper side of the center sills. The shaft 0 is operated by means of a capstan-head cl, which is provided with suitable sockets to receive an operatingbar. At the inward side this capstan-head is provided with ratchet-teeth adapted to be engaged by a pawl whereby in operating the doors the shaft will be held from turning while the capstan-bar is being changed from one socket to another.

When the doors are closed, the crank-arms 'S and Q on the sheaves will stand slightly to one side of the line which passes through the center of the shaft and the centers of the crossheads F. In other words, the crank-arms will have been made to pass centers, and in this position the upper link J will be thrown against the vertical web P and the lower link against the web R, so that no further rotation from left to right (see Fig. 5) will be possible. It will therefore be evident that the pressure of the contents of the car, which tends to open the doors, will only serve to lock them more tightly in their closed position. In order to throw the doors open, the sheaves must be turned from right to left, thereby throwing the links J away from the webs P and R, and this can only be done by imparting motion to the reciprocating bars U. This motion is imparted to the reciprocating bars by the double sheave L, which is rotated by means of its chain connection with the operating-shaft 0. When the operating shaft is turned in the proper direction, one end of the chain which runs from the chain worm 6 around the sheave L will be wound onto said worm while the other end is being wound off, thereby imparting motion to the sheave L, which, by reason of the chain connection between the lower half of the sheave and the reciprocating bars U, is transmitted to said bars to draw one of the said bars toward the operating end of the car, and it will be evident that when one of the bars is drawn in one direction the other bar will bedrawn in the other direction by reason of the chain connections which pass around the sheaves K. When the sheaves have been given slightly more than a half-rotation, the crank-arms S and Q will again be thrown slightly past centers and the lower link J will be thrown against the outer edge of the web R, thereby preventing further rotation from right to left and causing the doors to be locked in their open position. This provides a full opening for the discharge of the contents of the car from the chutes and prevents the doors from swinging back and forth as the contents flow more or less freely from the car.

Having thus described my improved operating-gear and without confining myself to the precise details of construction herein shown and described, what I claim as my invention, and desire to secure by Letters Patent, is-

1. In a car of the type described, the combination, with the'chutes and hinged doors, of a door-operating system comprising crossheads sliding on guides located at the sides of the chutes, links coupling the cross-heads to the doors, and means operated from one end of the car for imparting motion to the crosshcads to open and close the doors. 2. In a car of the type described, the combination, with the chutes and hinged doors, of

a door-operating system comprising cross-' heads sliding on guides located at the sides of the chutes, links coupling the cross-heads to the doors, double crank-arms mounted between oppositely-disposed cross-heads, links coupling the crank-arms to the cross-heads, and means operated from one end of the car for oscillating the crank-arms to open and close the doors.

3. In a car of the type described, the combination, with the chutes and hinged doors, of a door-operating system comprising crossheads sliding on guides located at the sides of the chutes, links coupling the cross-heads to the doors, double crank-arms mounted between oppositely-disposed cross-heads, links coupling the crank-arms to the cross-heads, the double crank-arms being so disposed as to permit the links to pass one another, means operated from one end of the car for oscillating the crank-arms to open and close the doors, the crank-arms being thrown past centers when the doors are closed, and means for limiting the throw of the crank-arms after they have passed centers.

4. In a car of the type described, the combination, with the chutes and hinged doors, of a door-operating system comprising crossheads sliding on guides located at the sides of the chutes, links coupling the cross-heads to the doors, sheaves carrying double crank-arms hung between oppositely disposed crossheads, links coupling the crank-arms to the crossheads, said crank-arms being so disposed on the sheaves as to permit the links to pass one another, reciprocating bars extending along opposite sides of the sheaves, chains or cables running from one bar to the other around the sheaves, a sheave at one end of the system having double grooves, an operatingshaft running in from one end of the car toward said double sheave, a chain or cable passing around one of the grooves on said sheave, and means for winding the ends of said chain or cable on and off from the operating-shaft to impart motion to the reciprocating bars in one direction or the other.

5. In a car of the type described, the combination, with the chutes and hinged doors, of a door -operating system comprising double crank-arms hung to oscillate horizontally between the ends of opposite chutes, link connections between the crank-arms and the doors on each side of the car, the double crank-arms being so disposed as to permit the links coupled thereto to pass one another, a longitudinal shaft operated from one end of the car, and connections between said shaft and the crank-arms, whereby the crank-arms may be oscillated to open and close the doors.

6. A sheave for a door-operating system of the type described, having a vertical web projecting from one face at one side of the center, a shelf supported by said web parallel to the face of the sheave, a vertical web projecting from said shelf on the side opposite the first-named web, and crank-arms projecting in diametrically opposite directions from above and below said shelf.

In testimony whereof I have aflixed my signature in presence of two witnesses.
